The invention relates to alubricating ap paratusfor flanged wheels having a sleeve containing a consistent lubricant (grease) which 1s pressed out by a piston adapted to be moved by a. screw spindle. According to the invention, the. apparatus has a ratchet device for turning the screw spindle, with a ratchet wheel secured to said spindle, and working, through a revolving wheel, 1n cooperation with two coaxial spur-wheels having a different number of teeth, one of which is fastenedto the sleeve containing the lubri-' v cant, whilst the other is connected with a scale disc or dial, and is adapted to operate on the pawl by which the ratchet wheel is rotated, the whole device being so constructed that, during therotation of the ratchet wheel, the second spur-wheel is turned in relation to the first spur-wheel and the scale disc is al-soturned, and, in a position corresponding with the end of the stroke of the piston, lifts the pawl out of the ratchet wheel.

In Fig.1 of the drawing'one construction of the device is shown, by way of example, in longitudinal section.

'Fig. 2 is a section on II-lfin Fig. 1, Fig. 3 a plan of the devlce shown in Fig. 1.

The cylindrical sleevel contains the pis ton 2 and is closed at the top by a cap 3 and at the bottom by a ring 4 let into the sleeve,

into which ring is screwed a. spigot 5 through .w hich, the lubricant in the sleeve 1 is pressed out. In the middle of the cap 3 and rings the screw spindle 6 is journaled. The screwthread of this spindle fits in the piston 2. Parallel to the screw spindle 6 is arranged a rod 7 passing through the piston 2 and fas tended to the cup 3 and ring 4. On .a hub S of the cap 3 rotates a casing 9. At the bottom of this casing 9 is arranged a pin 22 to which is secured a spiral spring 23,,this spring being wound around a hub 24; of the casing and fastened at the other end to a pin 25 fitted to the cap 3 and projecting through ar slot in the bottom of the casing 9. The casing 9 is oscillated by mean-s of aring 10 and connecting rod notshown in the drawing for the pur- 3086 of operating the lubricating device, A cylindrical extension 11 0f the hub 8 is loosely surrounded by a spur-wheel 13 fastened to a ring 12; Immediately over this spur-wheel 13 is fastened on the same hub extension 11 a second spur-wheel 14 of the same diameter which has one or two teeth less than the spurwheei 13. VVithboth spur-wheels-lB 14:

i be lifted out of engagement with theratchet wheel 17.,

From the ring 12 projects a pin 26, elose to the circumferenceofthe ratchet wheel-17, into the forked' e'nn of the arm 27 secured to ascale disc or dial 28 turning loosely in' a hole concentric to thefspindle 6 providedin a lid 29closrng the casing 9 at the top. lhelid 29 has a circularscalc on the outside, or one. or two marhs. Atthe top of the screw spindle .G is provided alsquare 31 for attaching a crank, by which the spindle 6 can be turned for the purpose of moving the piston. into the top (b ck) end position. Fron'rthe-spigotb a hose/(not shown on the drawing) is fled-to a nozzle near the flange rim of the wheels of c a railway vehicle.

The manipulation and operation of thed-escribed device is as follows: r

Whilst the railway vehicle is travelling in curves the casing 9 is oscillated baclmvards and forwards. By sodoing the screw-spindle 6 turned by the ratchet device'18, 17, and by the rotation of this spindle the piston 2 is moved intermittently downwards (to the front). Each movement of the piston presses some lubricant out of the sleeve lto the place to be lubricated. During each m vement of 5 the ratchet wheel 17 the pinion revolves somewhat on the spur-whe l 14. As the number of teeth of this spur-wheel is a little'lcss than that of the spur-wheel 13, the latter will be moved through one or two teeth in relation to the spur-wheel 14 during each complete rotation of the ratchet-wheel 17. With the spurwheel turns the ring 12 which by means ofa pin 26 andarm 27 carries along the dial 28. From the position taken by the dial 28 in relation to the circular scale 30, the position of the piston 2 inthe sleeve 1 can be seen, so that this has taken place, the screw spindle cannot be turned-mechanically by the vehicleso that thepiston will'ndt be'advanced. Consequenb ly injury to the apparatus by negligent serv screw spindle is turned; by the handle :pro

vided to fit on the top end of said spindle.
